- d extractor or like mechanism which is adapt? ed to be moved along the track from tie to tie in accordance with the exigencies of the work.

One obj ect of the invention is to eliminate the necessity of manually lifting the spike extractor from one tie to the other, and another object is to facilitate the operation of locating the spike extractor with respect to the spike.

Other objects will be in part obvious and in part pointed out hereinafter.

In the drawing illustrating the invention and in which similar reference characters refer to similar parts,

Figure l is an elevation partly in section of constructed in accordance with the practice of the invention, and

Figure 2 is a plan View partly in sectionl of a detail and taken through Figure l on the line 22 looking in the direction indicated by the arrows.

Referring more particularly to the drawing, A designates generally a spike extractor p the usual handles K whereby said extractor,

may be manipulated and guided with respect to the work.

The parts so far described form no part of'vv the present invention and are herein shown rif I ,1 merely for the sake of illustrating one mode a spike extractor equipped with a carriagel spike extracting element, such as a pair ofof the application the invention of which? the following is a description. In accorda-nce with the present invention :means are provided to protect the operator 'against y laying devices, such vas the s the necessity of Vbodily lifting track; V

are wheels l) which may beattached to the arms by means of bolts 1Q so arranged as to also act as axles for the wheels P. Preferably the wheels P areprovided with flanges It at their ends Vto engage the sides S of al` rail T which the spike D serves to secure-to the tie E.. I Y

In order to normally hold theextractor retracted with respect to the wheels so that the lowermost extremitiesof the extractor, asm. for instance, the jaws @may passreadily over the ties VE in the absence of .manual pressure in adownwardly direction upon the handles K, rods V pivoted at one end to the arms extend upwardly in the direction of@ the cylinder G and are slidably vguided by laterally lextending guide plates VV which may be .suitably securedto the frame B.

On each rod V are arrangedsa pair of cup like members X and Y which-serve -as seatsd forsprings Zand b disposed about the rods' V.v Thesprings Z 'and are arranged concentrically with respect -to each vother fand are of the compression type so that they constantly tend to 'bodilyraise the extractor with e0 respect to Vthe wheels P.

In order that the tension of the springs Z and b may be varied the rods V are provided with threaded portions c for the accommodation of nuts l whereon the members X are seated.

In practice, whenever it is desired to extract aspike D from atie the extractor A may be wheeled into substantially the proper position so that 'the jaws C will, when openi-SO lie on opposite sides of the spike D. It then pressure be applied to the handles K or" the `porting and guidance of the apparatus by having a frame, of a pair o Wheels for the' The present invention has been found to mediate point on each arm and the frame to lift the frame relative to the wheels.

5. A tool carrier comprising a frame, a pair of arms extending therefrom and pivoted thereto, wheels mounted on the Outer end. of the arms, and means acting between an intermediate point on each arm and the frame to lift the frame relative to the wheels.

In testimony whereof Iy have signedthis specification.

be extremelydesirable for use on apparatus c vof this type, particularly'where, as that il-Y lustrated, the apparatus is' of considerable weight and where ordinarily more than one operator is required to lift it from one working position to another. Y

By equipping the extractor With a carriage,

such as that illustrated, the extractor re-V v quires only one yattendant for Zits operation and the Work of removing spikes may be greatly expedited for` the reason 'that the extractor may be readily shifted along the track and into the proper operative position without necessitating the simultaneous supthe operator.

I claim *1. In combination with a spike extractor having a frame, of a. pair of wheels for the extractor, arms pivoted to the frame and forming mountings for thewheels, rods secured at one end to the arinsv and being guided at their other ends by the frame,

and springs on the rods acting against the frame to lift the extractor relatively to the wheels.

2. In combination with a spike extractorA having a frame, of a pair of Wheels for the extractor, arms pivoted on opposite sides of the. frame and forming Inountings for the wheels, rods pivoted at one end to the arms and being guided at their other ends by the frame, springs on the rodsk acting against 'the frame to lift the extractor relatively to the Wheels, and means or varying the tension of the springs.

3. In combination with a spike extractor extractor and having flanges to Vengage the sides of a' rail, arms pivoted at one end to the` frame and at the other end to the wheels, rodspivoted at one end to the arms, guides on the frame to slidably receive the other ends of the rods, spring seats carried by the rods, springs acting against the spring Vseats and the guides to raise the extractor relatively to the wheels, and means for varying the tension of the springs.

4. A tool carrier comprising a `frame, aV

pair of arms in hinged relationship to the frame, a Wheel at the outer end'of each arm, and spring means acting between an inter-
